There was a time when it seemed like every new device had to have an always-on blue LED. Escaping blue light at night was an effort. These days small white LEDs are in fashion, which I find much more tolerable.
A big of black gaffers tape takes care of that for me. Electrical tape in a pinch. If I use white gaffers tape, it significantly cuts the light but is still visible when I'm looking right at it.
